Abstract

L’invention concerne un dispositif et un procédé de transition d’un mode de fonctionnement d'une femto station de base dans un système de communication sans fil. Le procédé consiste à, dans un mode de sommeil, confirmer si, oui ou non, des informations de demande de transition de fonctionnement sont reçues d'au moins un terminal; et, lors de la réception des informations de demande de transition de fonctionnement du terminal, passer dans un mode actif. Ainsi, la consommation d'énergie de la femto station de base peut être réduite et l'interférence provoquée par le fonctionnement de la femto station de base peut être atténuée.
